Abstract
The increasing attractiveness and trust on digital photography has given rise to new acceptability issues in the field of image forensics. There are many advantages to using digital images. Digital cameras produce immediate images, allowing the photographer to outlook the images and immediately decide whether the photographs are sufficient without the postponement of waiting for the film and prints to be processed. It does not require external developing or reproduction. Furthermore, digital images are easily stored. No conventional "original image" is prepared here like traditional camera. Therefore when
forensic researchers analyze the images they don’t have access to the original image to compare. Fraud by conventional photograph is relatively difficult, requiring technical expertise. Manipulation ofdigital images is simpler. With some fundamental software , a digitally-recorded image can easily be edited. The most of the alterations include borrowing, cloning, removal and switching parts of a digital image.

A simple and effective method for optimal antennaarray thinning employing a broadside-scanned maximum gainbeamformer is presented. Starting from a fully populated λ/2-spaced regular lattice, the array is thinned by progressively
“turning off” the element(s) with the lowest weight(s) of theweight vector realizing maximum gain. The accuracy and effectiveness of the method is validated against a rigorous combinatorial search method that can be used to find the optimalirregular array configuration solution in small to moderate-sized
arrays. Furthermore, to evaluate the robustness of the proposedapproach, the effects of beam steering have been investigated forlinear arrays consisting of 10–40 antenna elements as well. Goodresults can be obtained for close to broadside scanned arrays,which is of importance for the directly radiating arrays that are
currently being considered as modern satellite systems.
